How to deal with
the vibration screen plate cracking
Vibrating
screen is a stone processing production line is widely used in screening
equipment, but in the vibration sieve after running for a long time, easy to
appear crack and side plate of beam and rail beam fracture. Before both through
the replacement of the solution and the side plate cracking if the welding
process, will soon again cracks, Zhongxin to provide you a brief introduce side
crack treatment methods.
1, The
first test of the six angle bolt connection is reliable. Remove the side plates
on both sides of the angle steel and the upper reinforcing rivet bolt plate,
with the damage surface between the check plate and angle on. On the surface of
qualified cases, ensure justifyfull side crack.
2,
along the direction of the crack and the sieve plate vertical welding, welding
torch can not swing can is divided into 2 parts to be welded, and after each
weld with needle gun blow, eliminate stress and welding slag.
3, continuous vertical welding, each weld with
a needle gun combat, until the completion of the welding
4,
Keep Grinding, polishing, welding. Until a smooth surface and the side surface
flush.
5, In
a lateral grinding the weld. As little as possible to weld the weld. Just clean
up the weld. And the lateral base material can be exposed. Then weld the
inside.
6,
the top of side hole grinding holes on the weld shaping, ensure that all burrs
have been removed, no grooves and dents.
7,
finish the area of the coating grinding clean. Then in the side plate and the
reinforcing plate coated with primer. All painted on both sides. Will
strengthen the sieve plate is placed on the inside, and as much as possible to
install bolts, reinforcing plate weld repair area will be covered on both
sides.
8,
tighten the bolt, the strengthening of the board to drill holes, to ensure that
the crack is covered, in the hole into the riveting bolt.
